Hi, I am seeing ldap_add: Already exists errors on my site GIIS monitoring page. The last time this happened, the FNAL site was listed in the CERN BDII as FNAL-USCMS and as FNAL-LCG2. Judit was able to fix that and the problem went away. I don't think that is the case here. Has anyone seen these errors in other contexts? Thanks, Joe
